I have a complete set of Tokico Illuminas, Tein S-Tech springs and FCM bumpstops (don't remember the size) setup and ready to install into your NA Miata. These have less than 800 miles on them. I only removed them to jump on Emilio's Tein 9/6 special pricing a few months back. I'd rather not break them apart because I don't have a spring compressor handy and it's a royal pain in the ***.
Simply unbolt your old busted-*** suspension, put these in, and roll fly.
